SPOT WELDING BY LASER BEAM |
摘要 |
Method of and installation for spot-welding by laser beam, the method characterized in that the focusing means (3) undergoes displacement so that the point of focus (4) of the beam on the workpieces (4, 5) describes at least a path which is closed upon itself and of which the surface area of fusion obtained corresponds to the desired spot weld. The invention is applied to the welding of superposed workpieces. |
